CAN总线应用环境复杂多样，可能会出现各种异常情况。本文列举了常见的CAN接口异常情况及解决方法，帮您更加地分析及解决CAN接口应用问题。常见异常及解决方法1.两个节点近距离测试，低波特率通信正常，高波特率无法通信。可能原因：未加终端电阻。由于CAN收发芯片内部CANCANL引脚为开漏驱动，如，在显性状态期间，总线的寄生电容会被充电，而在恢复到隐性状态时，这些电容需要放电。如果CANCANL之间没有放置任何阻性负载，电容只能通过收发器内部阻值较大的差分电阻放电。

为什么手机电池要选择锂离子电池呢？和传统电池相比，锂离子电池充电更快，待机时间更长，重量更轻，功率密度更大，寿命更长。但我们需要知道一些有关知识才能让它更好地工作。锂离子电池循环充放电会导致内部腐蚀和电解液及电极的退化变质。和铅酸系统类似，锂离子电池充电器大多为限电压充电器，区别在于锂离子电池有更严苛的电压容限，充满电后几乎没有涓流或浮充电流，而铅酸电池的截止电压更灵活。锂离子电池的生产厂家有更严格的充电标准，因为锂离子电池不能承受过电压。
